During the aerobatic routine, two snap rolls to the right were accomplished. At the end of the second roll, the pilot experienced a sharp roll to the left. After leveling out the pilot complained of no elevator control. Altitude could not be maintained and, with the engine at full power, the airplane impacted into trees. The postaccident examination shows no mechanical defects that could not be attributed to the loss of control. Engine and flight control continuity checks normal. Evidence shows engine was running at a high power setting consistent with the pilot's account.
Probable Cause: The pilot encountered a tailplane stall. The factors involved were the pilot conducted a low altitude flight maneuver and encountered engine torque effect.
